The headline on the website Pravda trumpeted President Vladimir V. Putin’s latest coup, its nationalistic fervor recalling an era when its precursor served as the official mouthpiece of the Kremlin: “Russian Nuclear Energy Conquers the World.”

The article, in January 2013, detailed how the Russian atomic energy agency, Rosatom, had taken over a Canadian company with uranium-mining stakes stretching from Central Asia to the American West. The deal made Rosatom one of the world’s largest uranium producers and brought Mr. Putin closer to his goal of controlling much of the global uranium supply chain.

But the untold story behind that story is one that involves not just the Russian president, but also a former American president and a woman who would like to be the next one.

At the heart of the tale are several men, leaders of the Canadian mining industry, who have been major donors to the charitable endeavors of former President Bill Clinton and his family. Members of that group built, financed and eventually sold off to the Russians a company that would become known as Uranium One.
